Paver Sand Calculator
Paver sand is a coarse, sharp bedding sand spread in a thin, screeded layer to seat pavers and hold them level. Because it is a leveling course rather than a fill, one inch is usually plenty for a patio or walkway.
Bags are always rounded up. Order about 5–10% extra for settling and waste — this is a planning estimate only, not a guaranteed quantity. Density is typical; confirm the exact figure with your supplier.
Density
| Typical density | 1.35 t/yd³ |
|---|---|
| Range | 1.3–1.5 t/yd³ |
| Default depth | 1 in |
| Source | Reviewed default — dry coarse bedding sand ~1.3–1.45 t/yd³ (OmniCalculator; sand suppliers); wet sand weighs more. Confirm with your supplier. |
Worked example
A 10 ft × 10 ft area at 1 in deep is 8.3 cubic feet — about 0.31 cubic yards, roughly 0.42 tons at 1.35 t/yd³, or 17 half-cubic-foot bags. Add 5–10% for settling.
Use notes
- Screed a uniform one-inch bed over a compacted base, and do not compact the sand before setting the pavers.
- Use sharp bedding sand, not soft mason’s sand, so the pavers stay put.
- Sweep polymeric sand into the joints afterward — that is separate from this bedding estimate.
Frequently asked questions
How much sand do I need under pavers?
A one-inch screeded bedding layer over a compacted gravel base is standard. This tool sizes that bedding course; joint sand is estimated separately.
What kind of sand goes under pavers?
Coarse, sharp concrete or bedding sand. Avoid fine play or mason’s sand, which shifts and lets pavers sink unevenly.
Is paver sand the same as polymeric sand?
No. Paver sand beds the stones; polymeric sand is swept into the joints and hardens to lock them together.
